Yes, you should be able to uncheck the 68 DTC from setting the CEL.

Have a look under Malfunction

You might need to read the 11p PDF as I can't remember if you have to check or uncheck the box to mask the code.

Only VL400 has that I believe.

All the early EFI systems (VN-VS except ecotec) run in what is known as batch fire operation which means all the injectors fire (inject fuel) at the same time. This happens twice per engine cycle which is where you get the term double fire from. When the system changes to single fire the injectors o...

Don't know. Maybe they were willing to sacrifice engine life for another .1 per lap? Maybe more with less rotating mass it will accelerate faster?

I've been staring at this picture for a while now and am struggling to understand how this doesn't wreck the crank and valve train with no balancer?

Any one have any ideas how this would survive?

Maybe they have modified the crank and change it to internal balance?

You guys need to get onto the facebook groups for the L27/L36/L67 scene more often! The rails were posted on their through the design and manufacturing stage! It is 98% absolute pure specimens on those pages, but would be a real pleasure to have a lot of you knowledgable guys on there! Can you post...

Unfortunately I don't do facebook.

They make some L67 ones but the same issue, taper instead of ORB.

Definitely should have been ORB O ring fittings.

Could always contact them and ask/suggest? It wouldn't be hard to change the design.

There is not VE table in the V6 stuff as they are MAF tuned. On the stock VS V6 there are only the MAF tables. VT onward there are injector rate constant Vs mg/cyl tables that you can use to trim the fuel. The1 added these tables to the Enhanced VS tunes. See VS SC injector rate constant tables..png
